It's usually near the splash well. It will be covered in clear resin, and laid in while it's in the mold. Mine all have them. I don't know if it was for theft identification, or probably to keep things straight when they were being made.

i made 4 aluminum tags i stamped the # into, putting one under each gunwale, one on backside of dash, and one on inside of trans.
